Abstract
In this paper we propose a new approach to replace nonlinear ordinary differential equations by approximate cubic–quintic Duffing oscillators in which its coefficients depend on the initial amplitude of oscillation. It is shown that this procedure leads to angular frequency values with relative errors that are lower than those found by previously developed approximate solutions.
